The Project
The Fremantle Lake Project
Fremantle Lake is our flagship geologic hydrogen prospect in California, and the place where our models meet the ground for the first time.
Why here
Why Fremantle Lake?
Three things drew us to this prospect: a geologic system with the potential to generate hydrogen naturally, a base of existing subsurface data that shortens the learning curve, and strong local infrastructure that makes development practical.
Together, those conditions make Fremantle Lake an unusually promising place to explore a new source of reliable, domestic energy.

Reliable, local power
Why does this power belong on the grid?
California imports 20 to 30 percent of its energy from outside the state, according to the California Energy Commission. Power generated within California addresses that gap directly, close to where it is used.
Unlike solar and wind, geologic hydrogen is unaffected by weather, season, or time of day. That lets it serve as baseload power, the steady around-the-clock supply a grid depends on, rather than electricity that comes and goes with the sun.
Once operational, the project would be the largest clean source of hydrogen in the United States.
The path forward
What happens next at Fremantle Lake?
The project follows the same disciplined, phased program we apply everywhere: gather data, drill to confirm, analyze with independent partners, and pilot before scaling. The immediate focus is the first prospect, which will bring hydrogen to the surface and test our models directly.

Our commitment
Developed responsibly, with the community in mind
Our work is grounded in science, transparency, and responsible stewardship of the land and surrounding community. We engage openly with stakeholders and share our progress as we continue to learn more about the opportunity at Fremantle Lake.
The drilling itself uses the same long-established methods the local community already knows from geothermal energy. For an independent view of how hydrogen is handled safely, the U.S. Department of Energy publishes detailed guidance.
